RAILWAY-CAR DRAFT-RIGGING.

Specification of Letters Patent.

Patented Apr. 4,' 1916,

Application led February 6, 1915. SerialNo. 6,411.

Be it known that I, Jeux F. OCoxxon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and usefulV Improvement in' Railway-Car Draft- Riggingrof which the following is a. full',- clear, concise, and exact description, refer-l ence being had lto theaccompanying drawlngs. formlng a part of thls specification.

This invention relates to improvements 1nrailway cardraftriggings.

Anv object of the' invention is to provide a draft rigging simple construction and one wherein keys are employed as the-'stop' members.' l Another object ofthe invention. is t0 provide a draft rigging having a yoke formed of` commercial shape land-Yparticularly an Hly 2o. v

beam.-

Other objects of the inventionA will more fully appear from the description hereinafter.

In the drawing forming a part of thisv specification, Figure 1 is a vertical sectional view oty adraft rigging embodylng my 1mvprovements, the followers being lshown in sides'of which are secured longitudinallyA extending pla-'tes 1'1-11 having depending i portions 12 to the outer sides of whichare secured strengthening plat-es 13 havingv Llower tiangesp 14 and upper flanges 15, the latter being bolted to said sills 10. On the' inner sides of the plates 11 and above the lowerfaces of? the sills 10, are secured longitudinally extending` channels 16. The depending portions 12 and thtl plates 13 togcthel'form the draftsills'or draft lmembers and the same aia ,pr `)vided with a front set of elongated",upper and lower slots 17` and 18, an intermediate sot of upper and lower slots 19 and 20 and a rear sot of elongated l upper and lower slots 21 and 22. Through the front slots 17v and ,N18 extend transverse keys 117 and 118 respectively; throughthe intermediate sets. of slots 19 and 20 extend transverse keys 119 and 120, which keys are relatively fixed or stationary through the rear set of slots 21 and 22 extend transyerse keys 121 and 122 respectively) Mountedibe tween'the draft members is a yokedesig nated' generally by the reference A, see Fig. which yoke is in the form of an Hfbeam having; a central horizontal" web 23,V 'upper fianges` 2li-24 and lower fianges 2525. The upper andlowerfianges 24 and 25 are provided-with a set of front slots 217 and 218 through which extend the keys 117 and 118,. said slots being` substantially ofthe same length as the width of said keys'.` A. shui-lar series of upper and lower rearslots 221: and 222 are provided 'in the yoke through which extend the keys 121 and. 122.

An intermediate series of upper and lowerVVV slots 219 and 220 are provided in the yoke ,A through which the keys 119 and 120r respectively pass, the slots 219 and 220, however, being longer than the keysv to 'thereby permit the yoke` to move forwardly vover said keys which, as heretofore stated.v 'are stationar \,'.V The horizontal web 23 ofthe yoke hasv a rear opening 2G therein rand a central opening 27, the twov openings-being sopa rated an' integral portion 2S of the web. The front portion of the web 23 iS partly out away as indicatedfat. 30 andA in which is received thev rear end of the drawbar 31 which., as shown, vis provided with upper and lower shoulders 29-'29 engaged bv the rear edges of the keys 117 and-118. The openings 2G and 27 are provided for rear and front' followers 32 and 33 respectively 'which followers. in normal position of the parts asshown in Fig. 1. occupy'a substantially' central position in-said onenings. Each of the followersis provided on its inner. face with i1 wa-rdly extending upper andl lower bosses 34 on which are positionedtho inner ycoils 35 of the .twin arranged springs', the outer coils 36 of each springibe` ing placed over the coils as appears in Figs.v 1`and 3, the upper outer coil resting upon the connecting portion 28 of the web of the yyoke. Each of the followers`32 and 33 -is furthermore provided with slots 37 on .the outer edges thereof which'engage and slide upon the edges of the web of the yoke yoke and yet/are permitted' to slide back and forth thereon, the position of the front follower under full bud being shown,4 in Fig. 2. Interposed between the front follower 32 and the rear end of the drawebar`31 are upper and lower blocks 38-38 which are in- .5 erposed horizontally between the keys'119 and 120 and the portion 39 of the web 23 which is left between the'central opening 27 j move, inasmuch as it is held by. the keysI 119 andl 12() which, in normal vposition of the parts, occupy the'front ends ofthe slots 219,-and 220. The inward or vbutiing' move.-

mentof the draw-bar is limited bythe en gagement of the draw-bar with said.'l:eys-

i 119 and 120and also by the Ydraw-barengaging the web portion 39 and thefrontfollower engaging the .connecting web 'portion 28; Under draft, the draw-bar shoulders engage the keys 117 and 118 thereby pulling the' same forwardly, these keys in turn pulling the yoke A forwardly and thus the rear keys 121 and 122. 'The rear ,follower 33 is 35. thus moved forwardly andI compresses the springs between it and the front follower `32 'which isv held from forward movement l by the keys 119 and 120.

From the-preceding description it will be 40 seen that my improved draft rigging avoids the use of side castings; it employs a cheap yet strong yyoke which can easily .be made :from a commercially rolled shape by merely punching the proper slots and openings.

therein; the draw-bar may be disconnected or removed by merely taking out the-key 118; the entire device may be dropped down by removing all theA keys; and theyoke A` not only servesits normal function of a 5.0 yoke but in addition coperates with the,V

keys in supporting the parts of the draft f jeal'..

embodiment of my improvements.` yet vitwill be understood that changes and modifica-Y tions may be madewithout departingfromy the spirit tof fthe invention and alf such. v.changes and modifications are contemplated 6.0:,asf come within'the scope ,of the .claims ap-v ,pended hereto.
